The invasive pest papaya mealybug (PMB) (Paracoccus marginatus) results in high yield losses and increased production costs for smallholder farmers. In Kenya, PMB was first recorded in Mombasa in 2016 and has since spread to become a serious pest, resulting in severe yield losses of between 57% and 91% and household economic losses of £2,224/ha (USD 2,809) annually.
